----------------------------------- krishon Sat Sep 27, 2003 11:18 am find the root of one number to the other ----------------------------------- well for example 3^1/4 which is the same as 4 root 3....wut function would i use to do that? ----------------------------------- rizzix Sat Sep 27, 2003 11:57 am ----------------------------------- public static double Math.pow(double a, double b); Which is defined in the java.lang package.. so no imports necessary. Raises the first arg to the second, i.e: a^b ----------------------------------- krishon Sat Sep 27, 2003 6:32 pm ----------------------------------- no not that one, its something else...here let me copy the question out, maybe it should make a difference. Create a class called Number***. This class should have an instance variable, called num, that will hold an integer value that will be the basis for all operations using this object. You should have a constructor that initializes num to hold the base value. Your class should include methods that will use various methods from the Math class to do the following: a. A method that will return double the value of the num value. Call this method double(). b. A method that will return square the value of the num value. Call this method square(). c. A method that will return the square root of the num value. Call this method root(). d. A method that will take a parameter and return the quotient of the parameter divided by num rounded up to the nearest integer. Call this method divUp(). e. A method that will return the value of num to the power of a parameter. Call this method power(). i've done all but e ----------------------------------- Tony Sun Sep 28, 2003 1:11 am ----------------------------------- Math.pow(num,argument) ? ----------------------------------- krishon Sun Sep 28, 2003 9:30 am ----------------------------------- that one wuz for b.... ----------------------------------- rizzix Sun Sep 28, 2003 11:18 am ----------------------------------- whats wrong with this.. you using the same method: pow. but ur using it differently (sort of). And the question does not say anything about using a method more than once. int a; int square() { return Math.pow((double)a, 2.0); } double power(int b) { return Math.pow((double)a, (double)b); } ----------------------------------- krishon Sun Sep 28, 2003 11:19 am ----------------------------------- i dunno..maybe i interpreted the question wrong...ok i'll take ur way ----------------------------------- rizzix Sun Sep 28, 2003 11:30 am ----------------------------------- woops i think i read ur question wrong. the methods are instance methods and affect (or work on) an instance variable..
